HAULING errnnarusj To all whom it may concern: v ,Be itknown that we, J OHN DAVIES, a subject of theKing of England, residing at lwiskin, Mountain Ash, -WVales, in the King dom of England, and JOHN DAVIES, a subject of the King of England, residingat Penrhiwceiber, Wales, in the Kingdomof England, have invented a new and useful Haul- I ing-Apparatus, of which; the following is a specification.

,Theobject of the'present invention is to constructa'reliable hauling-apparatus which f or other-fixed point.

I v a, isoperated by a hand-lever.

According to our invention we construct a grooved chain-wheel on one or both faces with, an annulus of ratchet teeth. This wheel is'mounted on an axle carried by the ends of a forked bracket, which-can be sc- I The bracket carries a spring-pawl which rides over the chain and I toothed wheel and prevents these latter from running back. A forked operating lever is pivoted on the ends of the said axle and is 25v ries at its ends one or two spring pawls to engage the ratchet teeth on. one or both faces prolonged beyond the axle. This lever carof the toothed wheel. The operating lever may be made in two parts pivoted together near to the toothed wheel, and it may. b'e'so constructed thatit acts as a' rigid lever for driving thetoothed wheel, but when being pushed backward preparatory to another ing a weight along th'e'ground.

operative stroke, the outer longer part moves backward before it causes the shorter part to follow. This construction enables the inner end of the longer part of the lever to press upon the chain during the driving stroke and to slip over the chain during the return stroke.

In the following description it is assumed that the apparatus is arranged with'the toothed wheel in a, horizontal plane for haul- The invention is illustrated in the. accompanying drawings, in wl1ich': Figure'l is a plan of the complete apparatus, part of the operating lever being broken away; Fig. 1 18 a section on the l1ne 11 of Fig. 1; Fig. 2 a view showing the toothed wheel half in elevation and half in section on the line 22 of Fig. 1; Fig. a section on the line 33 of Fig. 4, and F 1g.

of its faces with ratchet teeth a and it is mounted on (the axle c passing through the arms of a bracket (Z and the forked part c of the operating lever. These three parts, a, d,

. c, are secured together by nuts 0 screwing on to the ends of'the aXle c.

Theforked bracket cl fits over the wheel a and is formed with an aperture d at one end by means of which it may be connected to a beam or other fixture. .The bracket 03 is recessed at (Z to receive a pawl f pivoted to the'bracket cl. at 0Z Two abutments d are provided against which the pawl f bears when drawn'backward by a spring d fastened at one end to the pawl f and at the other end to the. pin 03 passing throughlugs P. The pawl f is formed with a groove 7 at its rear to allow itto pass more readily over the projecting'links of the chain. The pawl f is preferably provided with a ring (Z to enable it to be pulled out of engagement with the chain 72 when it is desired to rotate the wheel a backward. The forked part c of the operating lever E fits outside the bracket (Z and has lugs e to receive a bolt 6 by which the lever-E is pivoted to the part c. The inner end of 'e is beveled at e to enable it to approach more closely the bracket (Z; At the ends of the forked part c are formed recesses 6* to receive pawls c pivoted on the pins 6 A suitable spring is employed between each pawl e and one side of the recess 6 to keep the pawl in contact with the ratchet teeth a When the lever E ismoved in the directtion of the arrow in Fig. l, the parts 1 and e move'as a solid lever and its end E is in contact with the chain 12, but when the lever E is moved in the opposite direction to the arrow, it turns on its pin or bolt (2 sufficiently to enable the end E to pass over the links of the chain. In this last mentioned position the lever E bears against the solid back 6 of part e and carries same back. By reciprocating the lever E the wheel a is intermittently rotated and moves the chain 5, which may be attached directly to the article to be hauled. Oi We pass thetehai nt reund a pulley g and'connect its end to a link it mounted on the bolt 0. The pulley g Q is provided with a heck g to enable it to be attached to the article to behauled. The
